    About Air Preparation
    industrial info icon

    Customize your air preparation system with dryers, filters, and other purifying parts.

    Wilkerson Modular Compressed Air Regulators

    Set and maintain the pressure of your compressed air. These regulators connect to other Wilkerson units of the same series with joiner clamps (sold separately)—even if the pipe sizes are slightly different—so you can customize your air preparation system. They’re relieving, so they will exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.
    Relieving Regulators

    Mounting Brackets—Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
    Joiner Clamps—Joiner clamps (sold separately) create compact, airtight connections between components. All include a wall-mounting bracket, except for clamps in the R90 series.
    End Block Sets—End block sets (sold separately) allow you to swap out components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.

    Diaphragm Assemblies
    Fit a nonrelieving diaphragm assembly to these regulators to stop them from exhausting excess downstream pressure. They’re helpful if you’re using a gas you don’t want automatically released into the air, such as an expensive noble gas.
